WATER-MOTOR.

SPECIFICATION forming part of Letters Patent No'. 396,069, dated January15, 1889.

Application filed September 24, 1387. Serial No. 250,608. (No model.)

To all wiz/m it may concern:

Be itV known that I, BYRON B. Bowan, a citizen of the United States,residing at Bainbridge, in the county of Decatur, Georgia, have inventedcertain new and useful Improvements in XVater-illotors, of which thefollowing is a specification.

The object of my invention is to provide an improved apparatus forntilizin g water-power to drive machinery.

My invention consists in an improved organization ofiiistrtnnentalities, whereby friction is reduced to a minimum, themaximum power of the water utilized, and the apparatus rendered si rong, durable, and reliable in every respect.

In the accompanying drawings, Figure l is a vertical central section ofa water-motor embodying my invention; Fig. 2, a side view with the casing in section.

In the drawings my invention is shown embodied in that class of motorsin which an endless belt carrying buckets passes over pulleys within asuitable casing.

The pulleys A A are arranged, respectively, at the bottom and top of theapparatus, the upper pulley being preferably located directly over thepulle.,v A and a little above the water-level in the top of the penstockor water-suppl y. Any suitable frame-work may be used for supporting thepulleys. The upper pulley, A, is preferably mounted in adjustablebearings C, so that it may be raised and lowered to tighten or loosenthe belt. The lower pulley is inclosed in a casing, D, that closelysurrounds it, and is provided with an entrance-port, n, and adischarge-port, l). Over the entrance-port.y is a column, E, thatincloses one side of the lnicket-carrying belt. \Vh en the water entersthe port c., it rises in the column F. to about the water-level in thepenstock. The column of water in the column E aids materially ineffecting the rotation of the buckets, as a heavy pressure is thusafforded.

I have shown in the drawings a column, E', similar to the column E onthe vopposite side of the apparatus. This is simply for the purpose ofadapting the appara-tus to run in either direction, and may, if desired,be omitted.

At the entrance-port ([I preferably construct an anteehambcr, F, and inthe bottom thereof provide a waste-opening, F', having a valve, F2, sothat should any water be carried by the buckets beyond thedischarge-opening b it will drain out. The valve under theventrance-port is of course closed when the apparatus is ruiming.

The pulley A is provided on each side with annular sides g, that closelyfit the edges of the buckets G, and may be liared a little at theouteredge, as shown, to readily admit the buckets. As the belt of Vbucketsrevolves around the pulley A, the edges of the buckets come in closeproximity to the side rings, g, so as to form a water-tight joint, butnot so closely as to create undue friction. This arrangement preventslateral pressure. 'ithin the casing on each side I provide flanges 71,arranged to closely lit against the annular .sides g, just under theflared edge, to form water-tight joints, but with suttcient accuracy toavoid friction. The flanges 7L are located opposite openings c, and arejoined to the edges of the casing by offsets h, which tillup theopenings that would otherwise occur at these points. It is onlynecessary to have flanges upon one side of the apparatus-. c., oppositethe entrance-port-butI have shown two, as the drawin illustrate a duplexapparatus. The outer edges ol the buckets come in close proximity to thecasing, so that the water does not pass by the buckets, but the bucketsare carried with the water, thus obtaining the full power of thewater-pressure.

A water-stop, X, is secured to the casing directly over the pulley A andextends down between the side rings, g, close to the periphery of thepulley A. The water-stop is preferably triangular in cross-section, asshown, and prevents the flow oli water over the pulley and directs itinto the buckets on their downward movement. The pulley A is connectedwith apulley, ll, which may drive a belt, and thus communicate power toany desired point.

I claim as my inventionl. The combination, substantially as set forth,of a casing, the upper an d lower pulleys, the bucket-carryiing belt,the buckets thereon, the side rings on the lower pulley, and thewater-stop located over the lower pulley and between the side rings.
